The model on a view is null when using RedirectToAction

I am using RedirectToAction to load a new page after login and pass in the database model with it. 

RedirectToAction("AdministrationPortal", "Manage", person);

person.user model is a User class created by the entity framework. The model of person is 

class Person { 
    public User user { get; set; };
    public string roleType { get; set; };
}

I node the person object did hold the data at the time where RedirectToAction got called.

Don't know why when I user it on a portal page @Model.Person.user is null.

@model namespace.Model.Person

When I need to send a model in RedirectToAction, I simply pass id like (lets say you person has id):

return RedirectToAction("AdministrationPortal", "Manage", new { @id=person.Id} );

Then at controller:

public ActionResult AdministrationPortal(long id)
{
  //Get Person from DB
  var model=GetPersonById(id);
  return View(model);
}

I personally don't like using TempData but if you like to use it then:

TempData["Person"] =person; 
return RedirectToAction("AdministrationPortal", "Manage");

You cannot pass complex objects when redirecting using RedirectToAction.

It is used for passing the routeValues not the Model.

To maintain state temporarily for a redirect result, you need to store your data in TempData.

You can refer this for more info: passing model and parameter with RedirectToAction

TempData["_person"] = person;
return RedirectToAction("AdministrationPortal", "Manage");

Then

public ActionResult AdministrationPortal()
{
  Person p_model = (Person)TempData["_person"];
  return View(p_model);
}
